EFFECTS OF LATERAL FORCES WHEN PROPELLING ROUND SHARP CURVES

Tests were undertaken to investigate the effects of lateral forces arising from the propulsive effort in a train. The train make-up was 12 coaches of multiple-unit stock (weight 450 tons) with the tractive force provided by two electro-diesel locomotives used as electric locomotives. The purpose was to determine whether the speed restrictions on certain turnouts would have to be reduced for propelled trains, bearing in mind that turnout curves are not normally fitted with check rails and that the curved track in single and double slips cannot be fitted with check rails. The coach adjacent to the locomotives was instrumented to record distance moved, speed, axlebox lateral forces, bolster lateral displacement, and tractive effort at the auto-coupler. Load measuring baseplates were placed under the outer rail of the curve at six adjacent sleepers to record lateral forces and vertical loads.
